SELF-FEEDER FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 692,947, dated February1 1, 1902. Application inea october s, 1901. sain No. 77.954. No moda.)

To @ZZ whom t may concern.:

Be it known that we, J osIAH S. TUrrLE and CHARLES L. CooKsoN, citizensof the United States, residing at Kansas City, in the county of Jacksonand State of Missouri, have invented certain new and useful Improvementsin Self-Feeders for Ealing-Presses, of which the following is aspecification. Our invention relates tov self-feeders for 1obaling-presses; and our object is to produce a machine of this characterwhich is positive and reliable in action and of simple, durable, andcomparatively inexpensive construction.

To this end the invention consists in certain novel and peculiarfeatures of construction and combinations of parts, as hereinafterdescribed and claimed, and in order that it may be fully understoodreference is to be had to the accompanying drawings, in

zo Which- Figure lis a horizontal section of the power end of a press asequipped with feeder mechanism embodying our invention. Fig. 2 is a sideView of the same. Fig. 3 is a detail vview showing the feeder mechanismin a different position from that shown in Fig. 1. a section taken online IV IV ofFig. 1. Fig. 5 is an enlarged section showing the camforming a part of the feeder mechanism. Fig.

3o 6 is a side View of the loading-chamber end of the press as equippedwith the remainder of my feeder mechanism. Fig. 7 is a Vertical sectiontaken on the dotted line VII VII of Fig. 6, but showing the bracket atthe front end of the baling-chamber and the spring attached thereto inelevation. Fig. 8 is a detail view showing the presser-foot in itsdepressed position and the plunger as aboutto strike the same and forceit to the position 4o shown in dotted lines.

In the said drawings, 1 designates what is generally known as thegooseneck, wherein is journaled the power-shaft2, to which the sweep(not shown) is attached. 3 designates 4 5 the trip-lever, which mayembrace any desired number of arms, preferably equipped with the usualantifriction-rollers 3* and with supplemental rollers 3b, having theiraxes coincidental with rollers 3L and preferably 5o suitably journaledat .the lower sides of the trip-lever arms, as shown in Fig. 2.

Fig. 4. is

4 is the bed or reach, preferably in the form of a pipe and connected inany suitable manner lo the gooseneck-casting 1 and adapted to beconnected at its opposite end in the usual or any preferred manner tothe balin gcase end of the press.

5 is a casting secured to the bed contiguous to its front end, as shown,or in any other suitable manner and forming a shelf or support 6 for theusual reciprocatory pitman '7, which is caused to make its yin or powerstroke by the action of the trip-lever and is held in proper relationwith said trip-lever by means of a link 8, pivotally connected `at itsopposite ends to the pitman and lever 9, arranged in the path of andadapted to be successively operated by the trip-lever arms, said lever 9being journaled upon a stub-shaft 10, secured in and projecting aboveand below shelf portion 6 of casting 5, or said lever may be otherwisemounted, if desired.

To the construction thus far described we make no claim, as it iscovered in Patent No. 654,800, issued July 31, 1900, to WV. S. Livengoodandl G. Livengood.

.Iournaled upon the lower end of stub-shaf t 10 and just below shelf 6is a cam 11, the periphery of Which grows gradually more remote from itsaxis from one side of the latter to the other, and said cam ispreferably secured upon said stub-shaft by means of a Washer 12 andscrew-bolt 13, secured to the stub-shaft, said washer and bolt lyingwithin the recess 1/1 in the lower side of the cam. Of course the cammay be otherwise supported, provided one face or the other is leftperfectly free for the passage thereacross of a cable 15 or itsequivalent swiveled'or other- Wise pivotally attached at its front endto the cam, as at 16, for a purpose which hereinafter appears.

17 designates the baling-c'ase, of the usual or any preferred form,wherein reciprocates the customary plunger 18 of'pitman 7. (See Fig. 8.)

19 is the hopper for the baling-case and preferably located above thesame, the rear end of the hopper being open by preference in order thatthe feeder hereinafter referred to may operate therethrough. Extendingtransversely and horizontally of the press IOO near the rear and lowercorner of the hopper is a shaft 20, suitably journaled in bearings 21and provided at one end with a peripherallygrooved drum-segment 22,having a crossbolt 23 bridging the rear end of the groove for thepurpose of reliably securing the rear and upper end of the chain orcable 2l, rthe latter extending diagonally downward and forward a'ndpassing under the grooved pulley 25 for connection with the rear end ofcable'l. Upon the opposite end of shaft 2O is secured a double lever orcrank 26, one arm of said lever being formed with a pin 27, for apurpose which hereinafter appears. The opposite and normally lower endof the lever is connected by a pivot-link 28 to the sti re- .tractilespring 29, extending forwardly and vshaft 2O between bearings .21, andsecured rigidly to said arms are a pair of curved arms 33, formed neartheir upper ends and rear sides with rearwardly and laterally projectingshoulders or stops 3l.

35 designates a presser-foot for forcing the charge of hay or materialfrom the hopper into the baling-chamber, the same consisting,-preferably, of the steel or equivalent plate backed or reinforced by acasting 36, pivoted, as at 37, to and between arms 33 and adapted to belimited as to movement in one direction by contact with shoulders orstops 3l. Said casting is also formed with a central ear 38, projectingat the opposite side of the pivot vfrom the presser-foot, and said earis connected by a retractile spring 39 with the bolt 40, secured toshaft 20'for a purpose which hereinafter appears. \Vith the partsarranged as shown in full lines, Figs. 1 and 6, it will be apparent thatthe operation of the trip-lever in the direction-indicated by thc arrow,Fig. 1, causes the power or in stroke of the pitman and the rotationoflever 9 and cam 1l in the direction indicated by the contiguous arrow,Fig. l, the rollers 3fL and 3* of the trip-arm in advance-of thatengaging the pitman respectively engaging said lever and cam. Before thepitman has advanced materially the trip-arm in engagement with lever 9and cam 11 has moved from the position shown in full lines, Fig. 1, tothe position shown in Fig. 3, and as a result has through theintermediate mechanism described swung the feeder with extreme rapidi tyfrom the position shown in Fig. 6 to the position shown in full lines,Fig. S, and thus forced the charge of hay or other material from thehopper into the ybaling-chamber in advance of the plunger.

Asthe pivot or swivel point 16 of the cable, with the cam, passes beyondto the vertical plane of its axis and pulley 25 the spring 29, whichobviously stretched under the rotation of shaft 2O in the depression ofthe feeder, re-

dotted lines, Fig. l. It will thus be seen that the cam rotatesacomplete circle periodically, the first halt' of the movement beingimparted to it by the trip-lever and accompanied by v the descent of thefeeder and the last half being imparted to it by the retraction of.spring 29 and accompanied by the relevation of the feeder. It will alsobe seen Vthat the charge placed within the hopper is reliably andautomatically forced into the balingchamber ahead of the plunger, and,furthermore, that should the feederstick in the baling-chamber from anycause whatever its pivotal connection with arms 33 enables it whenstruck by the plunger to double up to the position shown in dottedlines, Fig. 8, and thus avoid injury to itself or the plunger. In itsdoubling or pivotal action spring 39 is obviously stretched, itsretraction immediately following the withdrawal of theplunger or theelevation of feeder-arms `33, this IOC parting from the principle ofconstruction involved.

Having thus described the invention, what we claim as new, and desire tosecure by Letters Patent,- is

l. The combination with a baling-press having a trip-lever, of a feedersuitably supported contiguous to the baling-case, a revoluble camsuitably journaled at the power end of the machine, a connection'betweenthe cam and the feeder whereby movement imparted to the former by thetrip-leveigis'accompanied by the advance or feeding movement of thefeeder, and means for synchronously restoring the' feeder to itsoriginal position and causing the cam to continue its movement until ithas described a complete circle, substantially as described.
